I'm still working on getting these to print correctly, but I think the model itself is in good enough shape to share.
Given the uniqueness and rare availability of the A1 ball detents, I wanted to work up this model for printing. You can print these with TPU filament, and they should be a drop-in replacement for the stock detents. I don't have an A1 currently to actually test these in the marker, so I'm curious for anyone who might want to give it a try.
If you would like for me to print them and ship them to you for testing, shoot me a PM. If you want to try printing them yourself, the thingiverse link is below.
